Abstract
A filtering system for filtering air is provided, which contains a filter for filtering particles out of the air and an ionizer that contains at least one electrode assembly upstream of the filter. An improved and longer filtering effect is obtained in that at least one of the electrode assemblies generates a negative corona discharge in a first operating mode, and at least one of the electrode assemblies generates a positive corona discharge in a second operating mode. An air conditioner and a vehicle that has such a filtering system is provided.
Claims10
A filtering system for filtering air, in particular for a vehicle, comprising
- a filter configured to filter particles out of the air, through which a flow path for the air passes,
- an ionizer, comprising at least one electrode assembly, through which the flow path flows upstream of the filter,
- wherein the respective electrode assembly comprises least one electrode and one counter electrode, which are connected to a voltage in order to generate a corona discharge in the air,
- wherein the ionizer is configured to provide the at least one electrode a negative polarity and the at least one counter electrode a positive polarity in the first operating mode of at least one of the electrode assemblies,
- wherein the ionizer is configured to give the at least one electrode a positive polarity and the at least one counter electrode a negative polarity in the second operating mode of at least one of the electrode assemblies.
